AXLE-SETTING MACHINE.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed July 16, 1905. Serial N 326,472.

To CbZZ whom it, may concern:

Be it known that I, JOHN WILLIAM ROB- ERTS, a citizen of the UnitedStates, residing at San Angelo, in the county of Tom Green and State ofTexas, have invented a new and useful Axle-Setting Machine, of which thefollowing is a specification.

My invention relates to improvements in axle setting machines adapted tosetting an axle intact or undetached from a vehicle, and the objects ofmy improvements are, first to afford a simple and easily adjusted devicethat can be operated on any style or shape of axle, second, acontrivance operating independent of utilizing the axle on vehicle for alever or bearing on the inside of the collar of the axle, third, torovide a machine not coming in contact with any part of the vehicle gearinside of collar of axle. I attain these objects by the mechanismillustrated in the accompanying drawing in which Figure 1, is a verticalview of one side of the entire machine in position on axle which is aduplicate of the part or side not shown. Fig. 2, shows more clearly theshape of inner end of lever B, in position on the axle. Fig. 3, is avertical right angle view to Fig. 1, looking on the line 1 2, Fig. 1,showing lever B, fulcrum block K, and axle H, held together by collarclamp h,

Similar letters refer to throughout the several views.

The acting or power lever A, with power similar parts screw a, adjustingor fulcrum screw 1), said lever A, is connected to a fixed lever B, bytwo links I, (one on each side of machine) with bolts or rivets at P P,

Fixed lever B, is clamped solid to the axle H, by a collar clamp 72,which prevents said lever B, moving or changing its position on the axleH, said lever B, being an extension of the axle arm H, on its outer end,Lever B, where it connects with link I, at P, has a beveled or slopingshape on its inside edge next to the axle; see F, Fig. 2, i

The purpose of having lever B, shaped like F, in Fig. 2, is to allow theend of lever B, at P, to move in toward axle when power is applied tolever B, at d, by means of power screw a, which when said power isapplied forces the two levers A and B, apart at d, which also causes apressure on fulcrum block K, at J, and also draws up on link I, at P P,thus forcing the end of lever B, at P, in toward the axle as the axlebends at m, Fulcrum collar clamp h, holds lever B, fulcrum block K, andaxle H, rigidly and firmly together preventing fulcrum block K, fromslipping on the axle; fulcrum block K, has a recess or pocket on itsupper or outer surface to receive the end of adjusting or fulcrum screw1), at J, which holds the power lever A, from moving in a horizontalline, out or in on the axle The two levers A and B, are connected by twolinks I, one of said links on each side of levers A and B, one end ofsaid links is connected to lever B, at its extreme inner end at P, andthe other end of links I, are fastened to lever A, just inside of theadjusting or fulcrum screw 1), causing the two links to have a slightangle to levers A. and B,when machine is in position to bend the axleinside of the collar at m; see Fig. 1;

When necessary to bend the axle outside of the collar of the axle on thewearing surface, lever B can be moved out-toward the point of the axleH, until the point at S, Figs. 1, or 2. is over or a little outside ofthe place to be bent or straightened, leaving lever A to retain itsformer position, this will bring the two links I, to a moreperpendicular or right angle position to levers A and B,

Fulcrum or collar clamp it, see Fig. 3,

which shows on the line 1 2, Fig. 1, has an adjusting or tighteningscrew g, on its lower side which bears against lever B, which holdsfulcrum block K, and lever B, securely to axle H, and holds said fulcrumblock K, and lever B, immovable on axle II, when operating the machine.

When power is applied by power screw a, to lever B, at d, it createsa'pressure at J, on fulcrum block K, and also draws on and up on leverB, at P, through connecting links I, causing end of lever B, at P, tomove in toward the axle inside of the collar at m.

I could accomplish the same results in operating this machine by placingfulcrum screw 1), on the inside of the collar of the axle provided,there was a solid bearing for the 'fulcrum screw 1), which is not alwaysthe case, as the upper surface of the axle is most always capped withwood, this would allow the two links I, to assume a right angle positionto levers A and B,

The fulcrum block K, could be dispensed with when the axle is to be setforward or back or up, if there is no clips or other obstructions tointerfere with. the bearing end of the adjusting screw 1), by placing ormoving power lever A, in toward the center of the IIO axle until links Iwere in a right angle to levers A and B, when said levers would not beinclined to want to move out or in on axle, 'as is the case when linksI, are in the position shown in Fig. 1,

I claim:

An axle setting machine comprising the combination of two horizontallevers practically parallel to each other of a power screw in the outerend of the upper or power lever being adapted to act on theadjacent endof the lower or fixed lever, a fulcrum or adjusting screw in the innerend of said upper or power lever, one end of a pair of twin links beingconnected to'the opposite sides of said adjusting screw and the oppositeends of said twin links being fastened to the extreme inner end of saidlower or fixed lever, a clamping collar that clasps said lower or fixedlever and a fulcrum block rigidly to the axle means for tightening saidclamping collar, a pocket or recess in the upper surface of said fulcrumvblock being adapted to receive and retain the end of said fulcrum oradjusting screw.
